6. How good was this quiz?

  • wait, is that a squirrel?
  • meh
  • simply fabulous
  • it was very good, thank you for asking

7. The products of the photolysis (splitting) of water are...

  • O2, H+ and an electron
  • H+ and an electron
  • OH-, H+
  • O2, H+ and a neutron

8. What is the function of light in the light-depedent reaction?

  • photolysis of water, to reduce glycerate-3-phospate, to make ATP
  • To make ATP, photolysis of water, to excite an electron in chlorophyll
  • To reduce CO2, to make ATP, to excite an electron in chlorophyll
  • To make ATP, photolysis of water, To enable the chlorophyll to take up an electron

9. As the electron moves down the electron transfer chain in the light-dependent reaction it...

  • loses energy
  • gains energy

10. In the calvin cycle, some of the Triose Phospate created is converted into glucose. What is NOT a possible use of the glucose produced?

  • Conversion into starch for storage
  • Making proteins
  • Nitrification in roots
  • Use in respiration

11. Why is hot methanol used to drop samples of photosynthesising algae into in the Calvin lollipop experiment?

  • Because it is a limiting factor to photosynthesis
  • Because it instantly stops the reaction by denaturing enzymes for photosyntheis
  • Because it instantly stops the reaction by boiling the water present in the algae
  • because it allows substances into which C14 is incorporated to be identified

12. Where does the light-independent reaction take place?

  • In the stomata
  • In the stroma
  • In the chloroplast membrane
  • In the thylakoid membrane of the chloroplast

13. What two products from the light-dependent reaction are used in the light-indepedent reaction?

  • ATP and NADPH
  • O2 and ATP
  • O2 and NADPH
  • NADPH and H2O

14. Why is the rate of photosynthesis not equal to the net uptake of CO2 by a plant?

  • Because some CO2 produced in respiration is used for photosynthesis
  • Because venus flytraps are carnivores
  • Because the rate of photosynthesis increases with temperature
  • Because CO2 is used only in the light-indepedent reaction

15. 'The rate of photosynthesis is affected by the factor whose level is at the least favourable value' this is called the...

  • least favourable factor
  • limiting factor
  • stopping factor
  • limited factor
